AI Agent Developer Manus Raises Over $500M

Manus, the developer of the eponymous AI agent, has announced a funding round exceeding $500 million.

The round was led by private equity firm Boyu Capital, with contributions from Tencent Holdings Ltd. and other investors. Bloomberg previously reported that the deal values Manus at approximately $4 billion, roughly double the price Meta Platforms Inc. reportedly offered last December.

Manus, originally launched as Butterfly Effect Co. Ltd. in 2022, gained viral attention with its multi-step task agent in early 2025. Meta’s attempted acquisition was scrapped in April 2026 after Chinese regulators blocked the deal. Since then, Manus has resumed operations as a standalone company, recently releasing Manus 2.0 which claims to reduce token usage by 23.2% while speeding up processing.
